Letters Patent No. 109,896, dated December 6, 1870.

IMPROVEMENT lN PUMPS.

The Schedule referred to in these Letters Patent and making part of the same.

To all whom it may concern.-

Be it knownthat I, WILLIAM HARTLEY, of Durand, in the county of Winnebago and State of Illl? nois, have invented a newand improved Pump; and I do hereby declare that the following is a full and exact description of the same, reference being ,had to the accompanying drawing and to the letters of reference marked thereon.

- This invention consists in certain details of construction, which will be fully described hereinafter.

In the drawing- Figure 1 represents a plan view of my improved pump, with thc'up'per chamber removed and-a portion of the separating diaphragm broken away to show the interior of the ram-chamber below. I

Figure 2 represents a central sectional elevation through theline a: a", fig. 1, the upper chamber being shown in place.

Figure3represcnts a partial sectional view of the ram and its packing through the line-a; x, fig. 2.

To enable others skilled in the art to make and use my invention,-I will now proceed to describe fully its construct-ion and operation.

A represents the ram-chamber, which is separated by suitable walls from the side supply-chamber B and delivery-chamber O.

It is itself divided int'otwo equal parts by a diaphragu'i, a, which hasa suitable central orifice, in which moves the ram A.

The supply-chamber B may be of any proper form, but is-preferably triangular in its cross-section, shown in fig. 2, and'is arranged with its larger area above the ram-chamber, in order that the passage of the water from the former to'the latter may be assisted by gravitation. It should be snfiiciently 'capacious to hold three or four times the quantity received into the rain-chamber at each movement of the ram.

1) represents the opening through which the water is received into the chamber B; and

b 11', valves, of which there may be one or more opening into each divisionot' the ram-chamber, through which the water is discharged.

The floor of chamber Q is also provided with a suitable number of valves, 0 0, through which the water is received from'thc divisions of chamber A;

Its delivery is effected through a nozzle, 0, as shown.

The valves 1) c consist of a disk, of leather or other suitable material, which rests over suitable orifices in the partitions separating the difl'ei-ent chambers. They are secured in place by means of a screw or headed pin, located at the center of the disk, upon' which is placed a spiral spring, as is clearly shown in the drawing.

To make a perfect joint between the ram and the scparating-diaphra-gm in which it moves, I employ metallic bearings, ca, fig. 3, which are secured in;

place and caused to bear against the surface of the ram by a spiral spring, a I

The operation is as follows: The ram A is given a reciprocatory movement in the diaphragm a by any suitable means, and water is admittedinto the chamber B through the opening 7).

As the ranrmoves to and fro in the chamber A, it produces a vacuum alternately in each division of the chamber, which is immediately filled, of course, by the water from chamber B. 1 The water is instantaneous in its action, because it, is moved not only by the pressure incidental to the creation of the vacuum, but it is also actuated'by its own'gravity, as the water-line of ehamber'B is above that of chamber A.

The large area of valve-surface attainable from the form and arrangement of the chamber, permits a large mass to be quickly moved. From the divisions of chamber A the water is 'forccd at each movement of the ram into chamber (Land thence discharged to any desired point by means of a pipe connected to nozzle 0'. v

One of the main points in the upper. air-chamber, beside the large valve area, is the bringing down of the atmospheric cushion close to the top of the valves,

or half way down the valve, so that they will strike the cushion at once without concussion.

By means of the spring uponvthe valve they are enabled to work rain'rlly without concussion.

From the construction described several advantages are obtained.- The water in the supply-chamber is delivered instantaneously to the ram-chamber and fills itperi'ectly full, whereby the-ram is enabled to deliver its full capacity at each stroke. The water is caused to fiow into chamber B in acontinuous instead of an intermittent stream. A large amount of valvesnrface is obtained, and the direction of the water in passing through the pump is not materially changed.

Having thus fully described my invention,

\Vhat I claim, as new, and desire to secure by Letters Patent, is-

"1.'The chamber B, constructed specifically as .described, and arranged as and for the purpose set forth.- 2. The combination. of the chambers B and A, when constructed as described, and arranged rela tively to each other, as and fertile purpose set forth. 3. The combination of the chambers A, B, and G, and ram'"A, when the parts are-constructed specifically as described, for the purpose set forth.

4. The ram A, with its packing a, and spiral spring a, as and for the purpose set forth.
